17 // TGrid //
18 // //
19 // Abstract base class defining interface to common GRID services. //
20 // //
21 // To open a connection to a GRID use the static method Connect(). //
22 // The argument of Connect() is of the form: //
23 // <grid>://<host>[:<port>], e.g. //
24 // alien://alice.cern.ch, globus://glsvr1.cern.ch, ... //
25 // Depending on the <grid> specified an appropriate plugin library //
26 // will be loaded which will provide the real interface. //
27 // //
28 // Related classes are TGridResult. //
